Abstract
Many aerospace alloys are sensitive to their composition thus cannot be chemically grain refined. In addition, only 1% grain refiners can act as nuclei for refining the structure. In this paper, physical refinement by intensive shearing above liquidus as an alternative technique will be investigated for AA7449 aerospace alloy. The results can open a new gateway for aerospace industry for refining their microstructure.

Additional information
The editorial board of Metals and Materials International has decided to retract this article. The retraction is due to the fact that the same data has been used in this paper as in a previously published paper without indication that the data had been published previously. Originally the authors of the paper were R. Haghayeghi and L. Nastac. Following the request from the second author indicating that he did not contribute to the paper and did not consent to being included in the author list either, the editorial board of Metals and Materials International has decided to remove the name of the second author, L. Nastac from the author list, with the first author, R. Haghayeghi’s consent.
